AMOS L. AVERY, OF BRADFORD, PENNSYLVANIA.

INJECTOR-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 488,646, dated December27, 1892.

Application filed February 1, 1892. Serial No. 419,891- (No model.)

Be it known lthat I, AMos L. AVERY, a citizen ofthe United States,residing at Bradford, in the county of McKean and State of Pennsylvania,have invented certain new and useful Improvements in Injector-Burners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to oil burners, and especially to that class inwhich the oil is converted into a gas, mixed with air and forced intothe boiler by a steam jet.

The object of my invention is to providea device that will be simple oi"construction and easy of operation.

The invention therefore consists in certain new and novel constructionsand arrangements, which will be fully described in the specification andpointed out in the claims, reference being had to the accompanyingdrawings wherein- Figure l represents a sectional view ot' my device,and Fig. 2 a section on line 2-2 Fig. l.

A represents the main barrel or part of the burner, which is preferablyround but may be any desired shape and is divided into two chambers a,the outer chamber, is for oil and entirely surrounds theinner chamber b,which is for steam, said compartments are separated by a Wall crpartition a. A is the oil delivery pipe and is connected to the ordinaryoil tank or reservoir (not shown) and supplies oil to the chamber a.

A2 is a pipe for conveying olf the gas, and is coupled to the upper sideof barrel A, extends backward and is provided with the cock B whichregulates the iiow of gas to the burner.

A3 is the steam supply pipe and leads from a boiler (not shown in thedrawings) to the steam chamber b as clearly shown in Fig. 2. Extendingthrough chamber?) is pipe b which is connected with the cock B by pipeh2 and T coupling a2. Into the outer end of this T coupling is securedby a nipple, another T coupling a4 carrying pipes c, c which supply hotand cold air respectively to the burner.

D is a drip pipe located on the under side ot' chamber a for the purposeof carrying off the water which is separated from the oil.

The operation of the device is as follows: Oil is admitted into chambero, through pipe A and steam into chamber b through pipe A2. The heat ofthe steam converts the oil into a gas which passes up through pipe A2and cock B to pipe b. The gas is drawn through the tubes by the suctioncaused by the escape of steam at the opening b2. The gas in passingthrough pipe b draws air through the coupling a4 in the same manner inwhich it is drawn to the mouth of tubebby the steam.

From the foregoing it will be clearly seen that the gas is thoroughlymixed with air before passing into tube b and mixed with steam at themouth of the burner.

What I claim is:

l. In an oil burner the .barrel A divided into two chambers a and b theformer encircling the latter, each having its respective supply pipe foroil and steam, said oil chamber having an outlet pipe A2 through whichthe gas is conveyed to pipe b substantially as shown.

2. In an oil burner a main barrelAhaving a steam and an oil compartmentthe former within the latter said oil compartment hav- `ing an outletpipe A2 which conveys the gas to pipe h said gas being drawn throughsaid pipes by the escaping steam jet at b2, andthe pipes c, c forsupplying hot and cold air respectively to the burner substantially -asdescribed.

In testimony whereof I aflix my signature in presence of two witnesses.
